You can put this solution on YOUR website! First name your variables.
Let S be the amount of soybean meal.
Let C be the amount of corn meal.
Now find the total weight equation.
1.
Now find the protein concentration equation.
2.
Now you have 2 equations with 2 unknowns.
Multiply eq. 1 by (-3) and add the equations together. lb.
Then from eq. 1, lb.
